@poleguy Thanks for reading my posts! :-) Here's the long story...

(1) Yep I wanted to get the PinePhone LTE Modem running with USB on NuttX. I built the USB EHCI Driver for PinePhone:

https://lupyuen.github.io/articles/usb3

(2) But the LTE Modem won't respond when I tried to enumerate the USB Devices. So I want to check over UART whether the LTE Modem is powered up and responding to simple AT Commands.

(3) Actually UART might be sufficient if we're building a simple Feature Phone with Phone Calls and Text Messaging only. (Which is my current objective)

(4) Genode OS managed to get the LTE Modem talking over UART. So I'm trying to reproduce their configuration:

(5) Right I'm not getting any meaningful output from UART. Thus the troubleshooting continues :-)
